1'0 @ZZ whom, z'z may concern.'

.Be it known that I, NICHOLAS ZOGG, a citizen of the United States, and a resident of New York city, in the county and State of New York, have invented certain new arid useful Improvements in Automatic Fillers, of which the following is a specification.

My invention consists of improved means of automatically supplying oil to self-feeding 1o lubricators for journals and other devices for and iny--auiomatio ller combined which automatic feeders are commonly used, the object being to avoid 'lling sofrequently as necessary on account of the small capacityl of the lubricators and to insure more regular feed of the lubricators, ashereinafter fully described, reference beingrmade to the accompanying drawings, in which* A Figure 1 is a side elevation of a lubricator as i'n use,

zmwith parts of the lubricator and filler-can broken out.' Fig. 2 is a sectional elevation of the filler-nozzle, on a larger scale, illustrating the operation. Figs. 3 to 6, inclusive, are side views of 'parts of the filler-nozzle, also on an enlarged scale, showing diierent forms of the vent-orifice of the nozzle.

In Fig. 1 of the drawings, a indicates a cominon form of lubricator for journals and other parts of machinery requiring lubrication, in the top ofwhich I make a suitable hole b, and at any suitable position a little higher than the lubricator,`but preferably directly above it, I provide a larger filling can or tank c, from the bottom of which is a feed-channel for. oil into the lubricator through a nozzle d, the discharge end of which extends into said lubricator through the hole b in the top, said nozzle being provided with a stop-cock c to close said passage when required. In the top 4o of the filler is an opening for supplying the oil which is closed air-tight by a cap f when cock c is open, and any suitable means of suspending the filler are provided, as the ring g and hook 7L.

N car but a little above the lower end of the fecding-nozzle cl is a small vent-opening e' through the side of the nozzle, which may consist of an orifice ofany form or a slot or notch, as fz", extending from the lower end of the nozzle upward.

I have found in practice that such a filler and nozzle so arranged with the lubricator,

for filling but without the vent-oriiice in the side, will fail entirely to feed the oil inta the lubricator, the filler being tightly closed, for owing to the equilibrium caused by the uniform pressure of air throughout the area of liquid in the nozzle no air will ascend through the open end of the nozzle to vent the filler, but with the orice above the lower end equilibrium no longer exists, because the force of down pressure at the end of "the nozzle is greater than at the orifice and air-bubbles enter through the orifice and flow upward, as indicated in Fig. 2, and thus ventthe filler and allow the oil to flow into the lubricator, the iiow being automatically regulated by the height-of the oil in the lubricator, which will vary only to the extent of opening the Ventoriiice slightly lto start the iniow of oil and then close it when raised by the ino'w sufliciently to cover the orifice.

I am aware that fillers having a Vent-tube provided inside of the nozzle and extending from the mouth of the nozzle upward into an air-chamber above the liquid in the nozzle have been used, as in the Patent No. 521,491, empty cans, from which there is free access of free discharge until the end of the nozzle is closed by the rising flood in the can, and I do not claim such device, which for lack of the unbalanced condition cannot eect my purpose of regulating slow feed, for whichthe small vent-tube is not only not necessary but will not work, because it will clog by capillary action.

I am also aware that Various contrivances of an airinlet tube have been employed in addition to the discharge-nozzle for venting cans from which liquid is to bc poured rapidly for filling other cans, lamps, and the like quickly, and I do not claim such devices broadly.

My invention is designed for a continuous slowly-feeding lubricator, and its special feature is a construction whereby it feeds and Vents through one and the same tube, and only one tube is used.

I claim as my invention- The combination with a lubricator, of the continuously-feeding automatic liller consisting of a can or tank adapted to be closed airtight, and the nozzle adapted for disnhargin IOO liquid from the can through its open lower the Vent-orice and the can, substantially as xo y end, and having a vent-orifice in the side near described. but above the lower end admitting the air Signed at New York city, in the county and for ventin g directly into the discharge-pas- State of New York, this 23d day of J uly.
